Hi,
I plan to change our FLA bank whith is 450a to two Lifepo4 drop in 230a in parallel. Are there other settings to consider for the charger than adjusting the bulk and float voltage and putting equal time to 0 as the manual has no information for Lifepo4 batteries? As the new batteries are drop in's, I would not have acces to the bms other than via bluetooth.TIA
Not sure on the Skylla but I know mppts have some preset profile options for LiFePo4. Personally I find those a little high but a good guide.
May want to also tweak absorption time ranges depending on balancing time of BMS. And temperature compensation if you've got that enabled.
Some batteries come with guidance on this in their datasheets for this as well as the normal float/absorption voltages.
Absorption 55.2v (which is 3.45v per cell)
Float 54v
My absorption time is 1 hour.
I believe victron's default LiFePO4 settings are higher for both, I cant quite remember but think they use 3.6 per cell.
It will be two 8 cell batteries for a 24V system, but your input of absorbtion value per cell and time is very helpfull. thx.
